Step-by-step explanation:

The answer is:

It will take 4.5 hours for two bricklayers to lay a total of 3150 bricks.

From the statement, we know that on Monday, bricklayers took 3 hours to lay a total of 4200 bricks.

So, we have that the rate of the four bricklayers is given by the following equation:

[tex]Production=Rate*Time\\\\Rate=\frac{Production}{time}[/tex]

[tex]Rate=\frac{4200bricks}{3hours}=\frac{1400bricks}{hour}[/tex]

Therefore, we have that the rate of the four bricklayers is 1400 bricks per hour, meaning that each bricklayer can lay 350 bricks per hour.

Now, to calculate how many hours it will take to the 2 bricklayers to lay a total of 3150, we need to divide the calculated rate (for bricklayers) by two, since there are only 2 bricklayers working on Tuesday.

So, calculating the time, we have:

[tex]Production=\frac{Rate}{2}*Time[/tex]

[tex]3150bricks=\frac{\frac{1400bricks}{hour}}{2}*Time[/tex]

[tex]3150bricks*2*\frac{1hour}{1400bricks}=Time[/tex]

[tex]6300bricks*\frac{1hour}{1400bricks}=Time[/tex]

[tex]Time=4.5hours[/tex]

Hence, we have that it will take 4.5 hours for two bricklayers to lay a total of 3150 bricks.

Have a nice day!

Given the rate of work from Monday, each bricklayer can lay 350 bricks an hour. Therefore, 2 bricklayers can lay 700 bricks an hour. It will take them approximately 4.5 hours to lay 3150 bricks.

First, we need to find out the rate of work done by each bricklayer. On Monday, 4 bricklayers took 3 hours to lay a total of 4200 bricks. Therefore, each bricklayer can lay 4200 bricks divided by 4 bricklayers divided by 3 hours, which equals 350 bricks per hour. So, one bricklayer can lay 350 bricks an hour.

On Tuesday, there are only 2 bricklayers, and they need to lay a total of 3150 bricks. Since each bricklayer can lay 350 bricks an hour, two bricklayers can lay 700 bricks an hour. To find out the time it will take to lay 3150 bricks, we divide 3150 bricks by the 700 bricks that two bricklayers can lay in an hour. This equals to approximately 4.5 hours.

Answer:

160π units³

Step-by-step explanation:

The volume (V) of a cylinder is calculated using the formula

V = πr²h ( r is the base radius and h the height )

here r = 4 and h = 10, thus

V = π × 4² × 10 = 160π units³ ← exact value

The required value of the wall after the window is made is 32 cubic feet.

Volume is defined as the mass of the object per unit density while for geometry it is calculated as profile area multiplied by the length at which that profile is extruded.

Here,
The total number of cubic feet in the wall before the window is made is,

6 feet (height) × 6 feet (width) = 36 cubic feet.

The window is 2 feet high and 2 feet wide, so its area is:

2 feet (height) × 2 feet (width) = 4 square feet.

To find the number of cubic feet removed to make the window, we simply multiply the area of the window by the depth of the wall, which is 1 foot:

4 square feet × 1 foot = 4 cubic feet.

Therefore, the total number of cubic feet in the wall after the window is made is,

36 cubic feet - 4 cubic feet = 32 cubic feet.

So the value of the wall after the window is made is 32 cubic feet.

Answer:

Option D.

Step-by-step explanation:

we know that

The inscribed angle is half that of the arc it comprises.

so

[tex]m<XYZ=\frac{1}{2}(arc\ XZ)[/tex]

In this problem  

The measure of angle XYZ is an inscribed angle

For this case we have the following equation:

We must create equivalent expressions in the equation, so that they have equal bases:

[tex]2 ^ {2 * (x-2)} = 2 ^ {3 * 6}[/tex]

If the bases are the same, then the two expressions are only equal if the exponents are equal:

[tex]2 (x-2) = 3 * 6\\2 (x-2) = 18\\2x-4 = 18\\2x = 18 + 4\\2x = 22\\x = \frac {22} {2}\\x = 11[/tex]

Answer:

[tex]x = 11[/tex]

Option D

Answer: OPTION D

Step-by-step explanation:

You need to remember the following:

[tex]a^x=a^y\\x=y[/tex]

 Then, you must descompose 4 and 8 into their prime factors:

[tex]4=2*2=2^2\\8=2*2*2=2^3[/tex]

Rewriting the expression:

[tex]2^{2(x-2)}=2^{3(6)}[/tex]

Now you get:

[tex]2(x-2)=3(6)[/tex]

Finally, you must solve for the variable "x".

Answer:

Congruent chords are equidistant from the center of the circle

Step-by-step explanation:

10.00 was the markup

Ellen's markup on the rose bushes is calculated by subtracting the wholesale price from the retail price, resulting in a markup of $10.00.

The question asks to calculate the markup of rose bushes that were bought at a wholesale price and then sold at a retail price.

To find the markup, we subtract the wholesale price from the retail price: Retail Price - Wholesale Price = Markup.

In this case, Ellen bought the rose bushes at a wholesale price of $24 and the retail price was $34.

So, the markup calculation would be:

= $34 - $24 = $10.

Therefore, the markup on the rose bushes is $10.00.

Answer:

3) -19 - 17i is our answer

Step-by-step explanation:

to solve A - BC we plug in the values given

A= -3 + 5i

B = 4 - 2i

C = 1 + 6i

-3 + 51i - (4 - 2i)(1 + 6i) is our expression. we can FOIL (4 - 2i)(1 + 6i) this expression out. FOIL stands for:

First

Outside

Inside

Last

i will highlight the terms i am using in the current step in bold and put the result next of those two terms next to the expression

F: (4 - 2i)(1 + 6i) = 4

O: (4 - 2i)(1 + 6i) = 24i

I: (4 - 2i)(1 + 6i) = -2i

L: (4 - 2i)(1 + 6i) = 12 < --- the reason why its 12 and not -12i or 12i is because i = √-1 and i² = -1

when we multiply -2i * 6i, we would have gotten a -12i², and i² = -1, so we are multiplying -12 by -1, which gives us 12 as the result

combining all these terms together and we have:

4 + 24i - 2i + 12

in the expression this is:

-3 + 5i - (4 + 24i - 2i + 12) < we need to distribute the negative sign into (4 + 24i - 2i + 12) and we now get:

-3 + 5i -4 - 24i + 2i - 12 < combine like terms (ex: i terms together)

-3 - 4 - 12 = -19

5i - 24i + 2i = -17i

the result of the expression is:

-19 - 17i

we cannot simplify this any further so this is our answer. the answer choice that matches this is 3, so 3) -19 - 17i is our answer

The result of the expression where i is the imaginary unit is -19-17i. Option 3 is correct

Given the following complex numbers A = -3 + 5i, B = 4 - 2i, and C = 1 +6i

We need to solve for A - BC

BC = (4 - 2i)(1 + 6i)

BC = 4(1) + 4(6i) - 2i(1) - 2i(6i)

BC = 4 + 24i -2i - 12(-1)

BC = 16+22i

Evaluate A - BC

A - BC = (-3 + 5i) - (16 + 22i)

A - BC = -3-16 + 5i - 22i

A - BC = -19 - 17i

Hence the result of the expression where i is the imaginary unit is -19-17i

Answer:

99.7%

Step-by-step explanation:

The 68-95-99.7 rule refers to what percentage of data is contained within ranges a certain distance from the mean.

68% of the data lies within one standard deviation of the mean

95% lies within two standard deviations, and

99.7% lies within three standard deviations.

Our mean here is 600, and our standard deviation is 120, so those ranges would be:

480-720 for 1 standard deviation

360-840 for 2 standard deviations, and

240-960 for 3.

Our given range is 240 to 960, three standard deviations from the mean, so the 68-95-99.7 rule tells us that this range contains 99.7% of the people.

According to the empirical rule, approximately 99.7% of people taking the GRE score between 240 and 960.

The student is asking for the percentage of people taking the GRE who score between 240 and 960 using the 68-95-99.7 Rule (also known as the empirical rule). This rule applies to normally distributed data and indicates that approximately 68% of data falls within one standard deviation of the mean, 95% falls within two standard deviations, and 99.7% falls within three standard deviations.

For the GRE, with a mean score of 600 and standard deviation of 120, one standard deviation range is from 480 to 720, two standard deviations is from 360 to 840, and three standard deviations is from 240 to 960. Using this rule:

68% of the scores fall between 480 (600-120) and 720 (600+120).

95% of the scores fall between 360 (600-2*120) and 840 (600+2*120).

99.7% of the scores fall between 240 (600-3*120) and 960 (600+3*120).

Hence, according to the empirical rule, approximately 99.7% of people taking the GRE score between 240 and 960.
